Abstract

The buckling detection head is completely encapsulated in an encapsulating material, thus making it possible to protect the emitting and receiving surfaces of the cells (21, 22, 23, 24) for emitting and receiving light signals. This arrangement provides a slot in which the absolutely smooth cable passes, making it easier to clean the head and protect the cells (21, 22, 23, 24). Other advantages of this arrangement are also described.

Le brevet de British Télécommunications Public Limited Company (GB) EP-1,015 928 décrit en détail un dispositif d'introducton d'un câble ou d'une fibre optique dans un tube. Ce dispositif comprend un dispositif de poussée mécaniques constitué d'une roue d'entraînement eî d'une roue d'appui, un dispositif de soufffage d'une pression d'air dans le tube permettant de transporter la fibre optique dans le tube ainsi qu'un dispositif de détection du flambage de la fibre en cours de pose, ce flambage provenant d'une différence positive entre là force de poussée exercée par le dispositif de poussée mécanique et la force de résistance de frottement de la fibre dans le tube. Un tel flambage en cours de pose est à éviter afin de conserver les qualités de transrnissson de la fibre Le brevet cité décrit complètement un tel dispositif d'introduction, son fonctionnement ainsi que les moyens électroniques permettaoî de rétablir les conditions de pose optimum de la fibre après qu'un flambage ait été détecté par le dîspositif de détection.British Patent Public Limited Company (GB) EP-1,015,928 discloses in detail a device for introducing a cable or an optical fiber into a tube. This device comprises a mechanical thrust device consisting of a drive wheel and a support wheel, a device for blowing air pressure into the tube for transporting the optical fiber in the tube as well as a device for detecting buckling of the fiber being laid, this buckling coming from a positive difference between the thrust force exerted by the mechanical thrust device and the frictional resistance force of the fiber in the tube. Such buckling during installation is to be avoided in order to preserve the qualities of transrnissson fiber The cited patent fully describes such an introduction device, its operation and the electronic means permetaoî restore the optimum laying conditions of the fiber after a buckling has been detected by the detection device.
Le dîspositif de détection de flambage décrit dans le brevet prècité comprend une fente profonde dans laquelle îa fibre est guidée, pouvant prendre notamment deux positions prèdèterminèes. une première positon de pose normale, sans tlamoage et une deuxième position avec un iêger flambage insuffisant pour détruire les qualités de transmission de la fibre Chacune de ces positions est délectée par un jeu de cellule d'émission et de cellule de réception d'un faisceau !umineux, îa présence ou l'absence du faisceau sur la cellule de réception de chacun desdits jeux indiquant une position correcte de îa fibre ou délectant une tendance au flambage.The buckling detecting device described in the aforementioned patent comprises a deep slot in which the fiber is guided, which can take in particular two predetermined positions. a first positon of normal pose, without tlamoage and a second position with a slight buckling insufficient to destroy the transmission qualities of the fiber Each of these positions is delighted by a set of transmit and receive cells of a beam the presence or the absence of the beam on the receiving cell of each of said sets indicating a correct position of the fiber or reveling a buckling tendency.
Le brevet précité montre que chacune de ces cellules d'émission et de réception est un élément discret, monté individuellement dans un logement qui lui correspond dans un support afin de former la tête de détection de flambage .The aforementioned patent shows that each of these transmitting and receiving cells is a discrete element, mounted individually in a housing which corresponds to it in a support to form the buckling detection head.
Vu qu'un dispositif d'introduction de câble est généralement destiné â être utilisé sur un chantier de pose et non uniquement en laboratoire, c'est-à-dire qu'il doit être apte è fonctionner en atmosphère humide et/ou poussiéreuse, à recevoir des projections boueuses, une telle disposition des cellules d'émission et de rêceptton comporte de nombreux inconvèfiients.Since a cable introduction device is generally intended to be used on a laying site and not only in the laboratory, that is to say it must be able to operate in a humid atmosphere and / or dusty, To receive muddy projections, such an arrangement of emission and reception cells has many disadvantages.
En cours d'utilisation, tes cellules étant placées dans des fentes de positionnement présentant des aspérités, des poussières peuvent se déposer dans ces fentes, encrassant rapidement fe système.In use, the cells being placed in positioning slots with asperities, dust can be deposited in these slots, fouling system quickly.
Le câble peut transporter des poussières ou autres éléments abrasifs susceptibles de rayer une ou plusieurs des surfaces d'émission ou de réception des cellules,The cable may carry dust or other abrasive elements that may scratch one or more of the transmitting or receiving surfaces of the cells,
Le nettoyage des surfaces d'émission et de réception des cellules peut s'avérer difficile, chaque surface étant à nettoyer individuellement, ce nettoyage pouvant détruire la surface d'émission ou de réception par âbrasion par une poussière lors du nettoyage, par ailleurs ce nettoyage esî susceptible de dérégler la posîtion de la ceîlule en cours de nettoyage.The cleaning of the transmitting and receiving surfaces of the cells can be difficult, each surface being cleaned individually, this cleaning can destroy the surface of emission or reception by abrasion by a dust during the cleaning, otherwise this cleaning It is likely to disrupt the position of the capsule during cleaning.
Le remplacement d'une cellule endommagée peut s'avérer compliqué, notamment pour le raccordement sur fe chantier des pattes de connexion de la cellule ; après échange de la cellule, il est nécessaire de régler sa position. Le but de la présente invention est donc de proposer de protéger Ja tête de détection de flambage, comportant tes cellules d'émission et da réception, afin d'éviter les inconvénients mentionnés ci-dessus des fêles de détection de flambage connues,The replacement of a damaged cell may prove difficult, particularly for connection to fe site of the cell connecting tabs; after exchange of the cell, it is necessary to adjust its position. The object of the present invention is therefore to propose to protect the buckling detection head, comprising the transmit and receive cells, in order to avoid the aforementioned drawbacks of the known buckling detection slots.
5 Pour ceci, te dispositif dlntroduction de câble optique comprend une tête de détection de flambage, telle que décrite dans la revendication 1 Des variantes d'exécution sont décrites dans les. revendications dépendantes.For this, the optical cable introduction device comprises a buckling detection head, as described in claim 1. Alternative embodiments are described in. dependent claims.
L'invention est plus précisément décrite ci-dessous, cette h\ description étant à considérer en regard du dessin annexé comportant tes figures où ;The invention is more specifically described below, this description being to be considered with reference to the appended drawing including your figures where;
la figure 1 est une vue de dessus en perspective avec coupe partielle d'une tête de détection de flambage selon l'invention, etFIG. 1 is a top view in perspective partly in section of a buckling detection head according to the invention, and
la figure 2 est une vue de dessous de la même tète de détection 15 de flambage.Figure 2 is a bottom view of the same buckling detection head.
La tête de détection de flambage 1 représentée à la figure 1 comprend une plaque de base 10 destinée à être fixée sur une portion du dispositif d'introduction de câble, par exemple par des vis de fixation passant par les trous 100. Le dispositif d'introduction de câble ainsi que 0 les vis de fixation ne sont pas représentés sur les figures. La plaque de base 10 est surmontée de deux blocs de détection 11 et 12, disposés perpendiculairement en saillie sur Ia surface supérieure de la plaque de base 10, les deux blocs de détection étant séparées par la fente 13 dans laquelle circule le câble. La fente 13 est imitée par les deux surfaces 110 ? et 120 se faisant lace de chacun des blocs de détection 11 et 12. La largeur de la fente 13, respectivement l'espacement entre les deux surfaces 110 et 120, est légèrement supérieure au diamètre maximum de câble susceptible d'être posé à l aide de ce dispositif d'introductionThe buckling detection head 1 shown in FIG. 1 comprises a base plate 10 intended to be fixed on a portion of the cable introduction device, for example by fastening screws passing through the holes 100. The device of FIG. introduction of cable and 0 the fixing screws are not shown in the figures. The base plate 10 is surmounted by two detection blocks 11 and 12, arranged perpendicularly projecting on the upper surface of the base plate 10, the two detection blocks being separated by the slot 13 in which the cable runs. The slot 13 is imitated by the two surfaces 110? and 120 being laced with each of the detection blocks 11 and 12. The width of the slot 13, respectively the spacing between the two surfaces 110 and 120, is slightly greater than the maximum diameter of cable that can be laid using of this introductory device
La défection de flambage se fait par deux jeux 2 des cellules 5ϋ d'émission et réception de faisceaux lumineux représentées en 21 22 et 23. 24 Le jeu de cellules 21 , 22 détecte la présence du câble en cours de pose alors qu'il circule dans la position haute de la fente 13 alors que le jeu de cellules 23, 24 détecte une position en léger flambage du câble alors que ce flambage le pousse en position basse de la fente 13The defection of buckling is done by two sets 2 of the cells 5ϋ of emission and reception of light beams represented in 21 22 and 23. The set of cells 21, 22 detects the presence of the cable being laid while it is moving in the high position of the slot 13 while the set of cells 23, 24 detects a position of slight buckling of the cable then that this buckling pushes it in the lower position of the slot 13
5 L'ensemble du dispositif, plaque de base 10 et blocs de détectionThe entire device, base plate 10 and detection blocks
11 et 12 est obtenu par coulage d'un matériau synthétique, par exemple une résine, autour des composants électroniques 21 , 22, 23 et 24, L'ensemble constitue donc un élément rigide et indéformable Le matériau synthétique utilisé peut être de n'importe quel type apte à cet ê usage, une contrainte étant qu'au moins les faces 110 et 120 imitant la fente 13, ou au moins les portions de ces faces directement en face de cellules 21 , 22, 23 et 24 soit translucide de manière à permettre le passage ded faisceaux lumineux entre lesdites cellules11 and 12 is obtained by casting a synthetic material, for example a resin, around the electronic components 21, 22, 23 and 24, the assembly thus constitutes a rigid and dimensionally stable element. The synthetic material used can be of any size. which type suitable for this purpose, a constraint being that at least the faces 110 and 120 mimicking the slot 13, or at least the portions of these faces directly opposite cells 21, 22, 23 and 24 is translucent so as to allow the passage of light beams between said cells
On voit donc que les faces 110 et 120 ne présentent aucune5 aspérité, son! absolument lisses et peuvent donc très facilement être nettoyées. Les surfaces d' émission et de réception des cellules 21 , 22, 23 et 24 sont protégées par une couche du matériau d encapsulage et ne peuvent donc pîus être salies ou endoπimagées Les positions relatives des cellules 2! 22, 23 et 24 étant fixées lors de l'enrobage0 desdites cellules par le matériau d'enrobage, ces positions ne peuvent plus être déréglées.So we see that the faces 110 and 120 have no5 roughness, its! absolutely smooth and can therefore easily be cleaned. The transmitting and receiving surfaces of the cells 21, 22, 23 and 24 are protected by a layer of the encapsulating material and therefore can not be soiled or endoπimaged. The relative positions of the cells 2! 22, 23 and 24 being fixed during the coating of said cells with the coating material, these positions can no longer be disordered.
On remarque en outre sur la figure 1 les pattes de connexion électriques 210. 220, 230 et 240 des cellules 21. 22. 23 et 24. Ces pattes sont soudées à des fils de connexion, non représentés sur les figures,5 ces fiîs ressortant du dispositif par la face inférieure 111 de la plaque de base 10,In addition, FIG. 1 shows the electrical connection tabs 210, 220, 230 and 240 of the cells 21, 22, 23 and 24. These tabs are welded to connection wires, not shown in the figures. of the device by the lower face 111 of the base plate 10,
En se reportant à la figure 2, on y voit un connecteur 25 portant une pluralità de tiges contacts 250.. ce connecteur étant fixé, par exemple au moyen de vis, sur !a face inférieure 111 de la plaque de base 10 du0 dispositif. Chacun des fils de connexion mentionné plus haut est donc relié par soudure ou tout autre moyen de connexion, â la tige de contact 250 qui lui correspond.Referring to Fig. 2, there is shown a connector 25 having a plurality of contact rods 250. This connector being secured, for example by means of screws, to the lower face 111 of the base plate 10 of the device. Each of the connection wires mentioned above is therefore connected by welding or any other means of connection, to the corresponding contact rod 250.
Ainsi donc, la liaison électrique des cellules 21 , 22. 23 et 24 étant faite en usine, un dérangement d'une des cellules 21 , 22, 23 ou 24 n'implique plus une délicate opération de soudure à faire sur le chantier.Thus, the electrical connection of the cells 21, 22. 23 and 24 being made in the factory, a disturbance of one of the cells 21, 22, 23 or 24 no longer involves a delicate welding operation to be done on site.
En variante d'exécution, il est tout à fait possîbfe de monter les cellules 21. 22, 23 et 24 sur le connecteur 25 avant d'effectuer l'opération d'enrobage, le connecteur 25 faisant alors partie intégrante de la tète de détection 1 ,As an alternative embodiment, it is quite possible to mount the cells 21, 22, 23 and 24 on the connector 25 before carrying out the coating operation, the connector 25 then forming an integral part of the detection head. 1,
Vu qu'il devient très facile d'installer une tête de détection t sur un dispositif d' introduction de câble par les vis placées dans les trous 100, la liaison électrique entre la tête de détection et le dispositif d'introduction de câble étant assurée via le connecteur 25, 250 et un connecteur femelle correspondant disposé sur le dispositif d'introduction de câble, on peut prévoir de disposer de plusieurs telles tête de détection , chacune ayant une largeur de fente 13 adaptée au diamètre du câble à poser,Since it becomes very easy to install a detection head t on a cable introduction device by the screws placed in the holes 100, the electrical connection between the detection head and the cable introduction device being ensured. via the connector 25, 250 and a corresponding female connector disposed on the cable introduction device, provision can be made to have several such detection heads, each having a slot width 13 adapted to the diameter of the cable to be laid,
On constate donc qu'une tète de détection de flambage, prévue pour être montés sur un dispositif diπtroduction de câble, telle que décrite ci-dessus remplit entièrement tes exigences fixées, soit facilité de nettoyage, impossibilité d'endommager les cellules d'émission ou de réception, position desdifes cellules indéréglable, facilité d'échange de la tête de mesure, ces divers avantages facilitant le travail des opérateurs sur un chantier de pose. It is therefore found that a buckling detection head, intended to be mounted on a cable introduction device, as described above fully meets the requirements set, namely ease of cleaning, impossibility of damaging the transmitting cells or reception, positioning of the cells foolproof, ease of exchange of the measuring head, these various advantages facilitating the work of operators on a job site.
